According to the current status, the construction industry in digital planning technology is at least at eye level with plant construction. For technical buildings, the "shell" is processed according to the Building Information Modeling (BIM) method, while the inner plants are executed according to the processes of digital plant construction. The common denominator between the two methods is an information model that can be applied by both industries.
The advantages of the integration for the operators and the project partners are:
Quality improvement through interchangeable models
Reduction of project costs through integrated data exchange
Extension of the life cycle through a high level of information technology
Information about the lifecycle
Project plans go through three main life cycle phases: Planning, execution and operation.
Complete and reliable building and system data form the basis for efficient and well-founded information procurement of the newly built facilities. For a continuous digital flow of information over the entire life cycle, model-based collaboration between all actors is required so that knowledge gaps between planning, execution and operation can be closed and prevented.
Over the course of the project, the models with the geometric and alphanumeric details and accuracies will increase. The LOG (Level of Geometry) and LOI (Level of Information) define the degree of information about the planning and operation-specific requirements for the various project phases. The aim is to provide a uniform and consistent description of the object data in terms of detailing and attributes. These requirements must be adapted and implemented to the respective project-specific aims.
Integrated method over the main phases
COBie stands for "Construction (to) Operations Building Information Exchange" and is used to collect essential project data for facility and plant management. COBie provides a unified structure as an Excel file for exchanging information about facilities and describes how project partners exporting and importing data to make the information practicable to other applications.
Planning / Data of construction
In the planning phase of construction, the models are provided at regular intervals by the individual project partners in IFC file format and compiled in the coordination model. Within the BIM method, all planning data for the exchange of information is stored in the model according to the requirements. For an extract of the data, COBie serves as a subset that summarizes the basic scope as a room and equipment list for the spatial and technical systems of an institution.
Planning in plant construction
Plant engineers create the master R&I flow chart as a planning basis and design their plant in a separate CAD tool. The subcontractors supply the 3D models in STEP format for the respective assemblies and the corresponding alphanumeric information is enclosed as a COBie information model. COBie is very similar in content to known project-specific equipment and spare parts lists. The big advantage is the international standard of this format, which can be created from the existing ERP, CAE systems.
Data acquisition during project execution
On the product level, the 3D models of the manufacturers are provided. These can be offered consolidated as IFC models in which the geometric data and the data sheet are digitally available as an information part. On the product level, however, not all manufacturers can yet create IFC files and supply 3D models as STEP files and the corresponding data sheets in addition to the physical products. As a supplement to the data sheets, COBie serves as an information carrier for the ordered components, which are read into the further software applications.
LIBAL solution for users
LIBAL® provides a secure and proven platform that maps digital twins of products that give customers control over the entire product life cycle of a plant or building. The respective "digital twin" is the central basis for cooperative & efficient planning, execution and subsequent operation. All partners involved are integrated into the project via LIBAL® and a cross-company value-added network of object and product data, including all associated documents. This means that all valid data and documents are available to those involved in the construction in real time and on all mobile devices. Project management becomes much more efficient.
